Must Have Tech Accessory! - USB Voltage Meter

There's probably nothing more prevalent in your drawers than USB cables, however not all USB cables are made the same. Sure, the $2 USB cable you got from the gas station is convenient, but don't expect it to work as well or as long as the more expensive ones. So is there a way to test these cables that won't break the bank or require you to do some DIY trickery? Of course! With a USB voltage meter not only can you test out cables but you can also test out power adapters and quick charging features!

Excellent information for the USB voltage meter use, and clearly presented. Very helpful! Appreciate no annoying/unnecessary background music. Subscribed.

I have this bought more than 5 years ago. And there is only Volt and Milliamps shown on the very basic numeric LCD. I was wondering if there is a protection circuit that protects itself from being shorted out from over voltage? Lets say somehow more than 5V up to 24V was fed to it?

A very useful video about cables! As you say, not all cables are created equal. I've certainly made the mistake of buying cheap ones which have poor quality connectors, etc. What I didn't realise for some time was that the cable became the limiting factor in the charging process - very limiting!

Hello, have you tested if the Data Blocker affect the maximum power that can be negotiated by the device?
Thanks!

I have about 30 usb cables, some are micro, some are type C etc, may I ask could you do a video on just checking the cables only as I want to recycle any bad ones that I am holding on to for no good reason?
